Well, looking at your profile your progress seems to be pretty fast already, if you ask me. But 10k in five months? I dunno, I certainly do think that this is possible, but bringing up the dedication and time to reach and hold that level from scratch seems pretty hard. Unless you're gifted or already otherwise accustomated to these kind of games.
On the other hand that's coming from someone who hasn't reached the five star level in six years. I'm not really what you could call an ambitious player (and poster) though and I'm lacking the knack for it after all, so don't think that much of my opinion, 'kay?
By the way, welcome to the forum.
Ehhh, is this thread considered too serious for OT? Doesn't really contain meta or any shiposts I've seen around here lately... yet...
